WILLIAM A. ROSE, OF PEEKSKILL, NEW YORK.

OAR.

Application filed March 31, 1921.

T 0 all whom it may concern Be it known that I, WILLIAM A. Rosa, acitizen of the United States, and a resident of Peekskill, in the countyof Westchester and State of New York, have invented a new and usefulImprovement in Oars, of which the following is a specification.

This invention relates to oars and particularly to such as are used inracing shells. To retain an oar in a definite and secure position it iscustomary to roll a strip of leather around the oar, building up a sortof leather flange thereon, the leather being secured to theoar by meansof nails, and the number of nails required to give the roll a requisitestiffness not uncommonly weakens and makes a breaking point in the oar.

The objects of this invention are to simplify the application of theleather, avoid the employment of weakening nails, and to give to theleather roll an unyielding metallic support. These objects are attainedby the means set forth in this specification and the accompanyingdrawings, in both of which like letters and numerals refer to similarparts throughout the several views. Referring to the drawings:

Figure 1 is a side view of an oar, and Fig. 2 is an edge View of thesame, both with this invention attached. Fig. 3 is a longitudinalsection of a part of an oar and of this device. Fig. 4 is a frontelevation of the device, with the car in transverse section. Fig. 5 is areverse view of the device. Fig. 6 represents this invention in itsrelation to a rowlock.

For the purpose of a stop on an oar no material is superior to leatherin the combined qualities of resistance to wear, noise prevention andreduction of friction. To admit of the easy application of the leather,of its easy renewal, and to reduce the width of the amount required to aminimum, a clamp A is shown, to be made preferably of aluminum to avoidweight, as shown in details in Figs. 3 and 5. The clamp is madepreferably in two parts, with lugs z i, i i, on each part for clampingtogether, as in Figs. 5 and 6.

When the two parts are bound together with screws, as Z Z, theyconstitute a tubular section m that is made to conform to the shape ofthat part of the oar which operates within the oarlock. This tubularsection is expanded into a flange n particularly shown in Fig. 3, whichterminates in a flange n Specification of Letters Patent.

parallel with the tubular section. \Vhen applied to the oar these twoflanges form chamber walls that cover the leather roll In applying theleather to the oar it is preferably laid on in strips ust long enough toprovide butting ends, as at 1, in Fig. 4., which shows the joint in thestrip 0. The only tacking the strips require is a short tack to justenter the wood, as at h h in the strip 0. Each required strip is put onin like manner, one over the other, with abutting ends, and tacked onlyat the ends. 7 f represent the tacks in the strip at, and g g the tacksin the strip 6. Three strips, as shown, are suflicient when good solidleather is used.

The clamp parts are so adapted that when they are screwed together overthe car they will exert a pressure upon the periphery of the leather,and also closely fit the oar. The roll and clamp are applied to the endof, and include the usual leather covering 6, that is applied to thepart of an oar that operates within the rowlock, as in Fig. 3. All thatis required to retain the clamp in place on the oar is a small screwthrough each half of the clamp, as at Z Z, Fig. 3. Fig. 5 represents thereverse side of the clamp, with all the parts that belong with it,including the wood-screws Z Z mentioned.

Figs. 1 and 2 giving two views of an oar, shows the clamps as appliedthereto. In Fig. 6, at 1, is represented a portion of an outrigger, anda 5 a swinging rowlock, to show the relation of the clamp to therowlock. The space within an oarlock is such that the bearing point 5 onthe oarlock can never get outside of the leather surface, that is, therecan be no contact between the rowlock and the metal flange of the clamp.The swinging part of the rowlock s is suspended between points 3 and 4of the bracket 8 the bracket being secured in the outrigger 1.

Having described the invention, what I claim and desire to secure byLetters Patout, is-

1. A stop clamp on an oar comprising layers of leather wound around theoar, one upon another and secured by tacks at the butting ends of thestrips, and a clamp in parts adapted to be secured together, the unitedparts constituting a tubular section to fit upon the oar, and cuppingflanges on the tubular section forming chamber walls to inclose one sideand the periphery of the leather layers, and screws through the tubularsection to secure the clamp in position on the ear.
